We bought a set of tires for my wife's car, brand new, from the Pep Boys around the corner from our house. After about 10K, we took at trip to east Texas and on the way back we got a flat. A roofing nail, in between the tread, not near the sidewall. We called the Pep Boys near our house and they told us to take it to one close to us, gave us directions and generally were 100% helpful. So I put on the doughnut, drove to this podunk PB, and went to the counter.
PB: Whatcha need?
ME: Tire plug.
PB: I don't think so, we don't do that.
ME: We bought the tires at a PB near us, we have road hazard, fix the tire.
PB: It's not that simple, buddy, we don't FIX tires, we replace them.
ME: Actually, unless you're planning on giving us a new free tire, it IS that simple.
PB: We'll see about that.
*car goes up, tire comes off, new tire goes on, bill prints out*
PB: That'll be $90.
ME: My arse.
PB: You want your car back or not?
ME: You want to keep your job or not?
*hand him the road hazard paperwork*
PB: This can't be real. We don't sell road hazard.
ME: My arse.
*called the other PB, got the managers talking to one another*
ME: Are you done eating your foot, or should I just get my spare keys and get on with the rest of my life?
PB: Here you go.
*keys in hand, I'm outta there*
What torqued me off the most, is that car now has one tire with 10K and three tires with 20K. All I needed was the old tire plugged or patched. And on the subject of plugs and patches:
1995 Buick Century, got a cut in the tire on the very edge of the tread where the sidewall starts. Cheerfully took it to an urban inner city tire shop where the nice non-English-speaking guy put a plug in it. $4 is all he wanted, I gave him $10. Drove for 30,000 miles like that until I sold the car, with this vibrant orange tire plug sticking out of the tire.
1989 Chevrolet Celebrity, got a screw stuck in between the tread, took it to Discount Tire where I had bought the tires, they patched it (not a plug, I was SHOCKED). It failed at 55mph the next afternoon, maybe 100 miles later. You bet your arse they replaced that tire for free.
